Action ofS-Carbamoyl andS-Thiocarbamoyl Derivatives ofL-Cysteine onL-Amino Acid Oxidase

Removal of Cysteine (an Aliphatic Amino Acid) by Natural Clinoptilolite

Amino acids have been extensively used in several processes of the pharmaceutical and food industries. Treatments for the recovery and reuse of the wastewaters generated from these processes are few and little known. This work aims at studying the influence of different variables on the sorption of L-cysteine, contained in aqueous solutions, on clinoptilolite mineral. L-Cysteine (Cys) was s...

Astudyon D-amino-acid Oxidase

Amino derivatives of mannuronic acid.

The widespread occurrence of amino derivatives of the sugars in products of plant and animal origin suggests the possibility that amino derivatives of the uronic acids may likewise be of importance. The uronic acids have the characteristic structures of both aldoses and aldonic acids, and hence, like the aldoses, might be expected to yield glycosyl amines [1] and like the lactones of the aldoni...

4-Hydroxypyridazin-3(2H)-one derivatives as novel D-amino acid oxidase inhibitors.

D-Amino acid oxidase (DAAO) catalyzes the oxidation of d-amino acids including d-serine, a coagonist of the N-methyl-d-aspartate receptor. We identified a series of 4-hydroxypyridazin-3(2H)-one derivatives as novel DAAO inhibitors with high potency and substantial cell permeability using fragment-based drug design. Comparisons of complex structures deposited in the Protein Data Bank as well as ...
